Tanking Niches

[PHG Dave]

Thanks alot guys. Does the tanking solution stick to the Silicon ok?
Should I be using acrylci Silicon or normal Silicon?

Thanks again.

Nothing much sticks to Silicon (Acyrlic and Silicon are two different materials)

Personally do not see the point in Silicon in the joints, if water gets through the membrane then it can go through the boards as they are only water resistant not waterproof.
Your original plan of Mapeband (or Dural's DURABASE Flex sealing tape) and Mapegum is perfect for the job

Thanks PHG.

Would the ditra matting be a better solution altogether? I understand this is applied with the same flexible adhesive used to stick the tiles?

Also (as posted in another thread) I have an 18mm marine ply floor. I laid this thinking it was the right thing to do. Unfortunately didn't seal it first.
I was thinking of using the ditra uncoupling membrane with this? Would that solve any issues with the ply? I am only waterproofing the floor to make it leak proof/splash proof as its a bath with shower above and not a dedicated wetroom?

Thanks again.
